IMPROVEMENT IN DARNING ATTACHMENTS FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 214,854, dated April29, 1879; application filed November 26, 1878.

To all whom it may concern:

Be it known that I, JOSEPH B. UNDERWOOD, of Fayetteville, county ofCumberland and State of North Carolina, have invented a new and usefulImprovement in Darning Attachment for Sewing-Machines, which is fullyset forth in the following specification and illustrated in theaccompanying drawings, in which Figure 1 is a side view of a portion ofa sewing-machine with my attachment in operative position. Fig. 2 is afront view of the same. Fig. 3 is a perspective view of my devicedetached from the sewing-machine.

This invention relates to the attachment, to the presser-bar of asewing-machine, of a device shaped to facilitate darning in place of theordinary presser-foot, said device being provided with ,an arm, soextended that it shall raise the presser-foot when the needle is raisedby contact with some part of the needie-bar.

A represents the darning-foot; B, the extended arm or projection O, theneedle-securing screw on the needle-bar; D, the needlebar; E, the screw,to secure the attachment to' the presser-bar'H; b, the hole, throughwhich screw E passes; c, the hole, through which the needle passes.

The operation is as follows: The darningfoot A having been attached tothe presserbar H and secured in position by screw E, which passesthrough hole b, when, in the action of the machine, the needle-bar Drises, the screw E strikes the arms B, and thereby lifts the foot A offthe material while the needle is out of the same, leaving the materialfree to be moved by hand the desired space required by the projecteddarn in any direction.

What I claim, and desire to secure by Letters Patent, is-

The darning attachment herein described, consisting of a plate, A,-bentas shown, and provided with hooked arm B, and perforations I) and c, asand for the purposes set forth.

JOSEPH B. UNDERWOOD.
